Depth of field is solely determined by the reproduction ratio and aperture - the focal length only affects the subject distance.
I will respectfully choose to disagree with you.
If you look at a depth of field chart (or better shoot pictures), there are numerous variables involved that affect the depth of field. At the same distance from a subject using the same aperture setting, you will have a much wider depth of field using a 35mm focal length than a 600mm focal length.
I have attached three pictures to this post to illustrate my point. Examples cite 35mm, 135mm, and 600 mm focal lengths. As you will see, the aperture and distance remain constant at f2.8 and 100 feet, but the longer the focal length is, the narrower the depth of field becomes.
